How to Fix Your Car Gauge and Dashboard Problems

The gauges in your car provide a lot of important information. They tell you information like how fast you are driving, if your lights are on, and if there are any issues with your engine. Depending on the car, the instrument panel can be quite detailed. In either case, if your car gauges are not working, it is a problem that needs to be addressed right away.

That said, how can you fix a troublesome gauge or dashboard? Let’s talk about that:

How to Fix Your Car Gauge and Dashboard Problems

If all the gauges in a car suddenly stop working, it’s typically due to a broken fuse or faulty wiring. To start troubleshooting, you’ll need to locate the fuse associated with the instrument cluster. Once you’ve identified the fuse, you can inspect it to determine if it has blown or needs to be replaced.

When you turn the key in the ignition, it is important that electricity is flowing through both sides of the fuse. To confirm this, a test light or multimeter can be used to ensure that the correct voltage is being generated. If you don’t have the correct car diagnostic tools or don’t feel comfortable checking this yourself, it’s best to take your car to a mechanic for a proper diagnostic.

If the fuse is in good condition, the next step is to test if the power is running to each of the instrument gauges. This may involve taking out the instrument cluster, which could be a challenging and time-consuming process, depending on the type of vehicle. After that, test the power of each of them. 

Keep in mind that if the gauges, along with the indicators and dash indicators, are not working, it could be a sign of a problem with the ground, assuming that the gauges fuse has already been checked and confirmed to be in good shape.

If the instrument cluster in your car is not functioning correctly, the gauges and lights on the dash may not work or may work inconsistently. To see if the issue is due to improper grounding, you can check under the dash with a flashlight. If necessary, you will have to take out the instrument cluster to verify the grounding.

In many cases, if you are dealing with electronic instrument clusters, your best bet is to have your car sent to the mechanic for repair. Otherwise, if they’re separate, you can go ahead and locate the source of the issue and get to work.

On the other hand, if a single gauge on your car isn’t working, it could be due to an issue with the gauge, the wiring, or the sending unit. If you are knowledgeable in car maintenance and repair, you may be able to figure out the issue and fix it yourself. Otherwise, it would be best to bring the car to a mechanic who is more experienced with such problems.

Let’s take your coolant temperature gauge as an example. Start by finding and unplugging the sending unit. Once the sending unit wire is detached, turn the ignition on. The coolant temperature gauge should display a cold temperature. Then, by connecting the sending unit wire to the ground, the gauge should change to show a hot temperature.

If the gauge behaves differently than what is expected, it is likely that either the sending unit or the gauge itself is bad. To find out which one, tests can be done in order to isolate the issue. Depending on the type of vehicle, the methods for testing the sending unit and the gauge may vary.


And there you have it. These are just some tips you can follow to address any gauge-related problem in your car. However, if you find the job to be too complicated or troublesome, feel free to send it to a mechanic. They can quickly identify the cause of the issue for you and send you on your way with a dashboard that you can rely on!
